allow disambiguation in the presence of empty hierarchies and
multiply-bindable subsystems this patch adds support for naming a new
cgroup hierarchy via the "name=" mount option

A pre-existing hierarchy may be specified by either name or by subsystems;
a hierarchy's name cannot be changed by a remount operation.

Example usage:

# To create a hierarchy called "foo" containing the "cpu" subsystem
mount -t cgroup -oname=foo,cpu cgroup /mnt/cgroup1

# To mount the "foo" hierarchy on a second location
mount -t cgroup -oname=foo cgroup /mnt/cgroup2

2: Easy to fix bug in converting code
3: Reduce clone of code in future

"force" mount option) if it detects that the HFS+ volume has a journal. 
The code was unconditionally assuming that the volume had a jounal if the
journal attribute was set in the volume header.  However, the volume also
has to have a non-zero journal info block to actually have a journal.

In this patch, I refactored the journal detection into a function since
the logic is used twice.  The journal detection also uses the better logic
to determine if there is a journal.

whether a volume has a journal or not.

The code currently mounts an HFS+ volume read-only by default when a
journal is detected.  One can force a read/write mount by giving the
"force" mount option.  The current code has this behavior since there is
no support for the HFS+ journal.

My problem is that the detection of the journal could be better.  The
current code tests the attribute bit in the volume header that indicates
there is a journal.  If that bit is set, the code assumes that there is a
journal.

Unfortunately, this is not enough to really determine if there is a
journal or not.  When that bit is set, one must also examine the journal
info block field of the volume header.  If this field is 0, there is no
journal, and the volume can be mounted read/write.


This patch:

The HFS+ support in the kernel currently will mount an HFS+ volume
read-only if the volume header has the attribute bit set that indicates
there is a journal.  The kernel does this because there is no support for
a journalled HFS+ volume.

The problem is that this is only half of what needs to be checked to see
if there really is a journal.  There is also an entry in the volume header
that tells you where to find the journal info block.  In the kernel
version of the kernel, this 4 byte block is labeled reserved.  This patch
identifies the journal info block in the header.

minix_dir_entry is used without checking first to see if the dirent is
really a minix3_dir_entry.  The inode number in a V1/V2 dirent is 16 bits,
whereas that in a V3 dirent is 32 bits.

Accessing it as a 16 bit field when it really should be accessed as a 32
bit field probably kinda sorta works on a little-endian machine, but leads
to some rather odd behaviour on big-endian machines.

However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set.  The default value is PIPE_A and can be wrong.  Set
up the pipe variable during driver initialization after hardware state was
read.

Also, the detection of the active display (and hence the pipe) is wrong. 
The pipes are assigned to so called planes.  Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS).  Change active pipe detection code to take into
account a status of the plane assigned to each pipe.

The problem is visible in the 8 bpp mode if colors above 15 are used.  The
first 16 color entries are displayed correctly.

info->screen_base - viafb_FB_MM

which is essentially the same calculation but done with physical instead
virtual addresses.

*->fbmem_virt
was replaced by
viafbinfo->screen_base
This is true for viafbinfo and viafbinfo1 as the par pointers are equal.

An early initialization of viafbinfo1->fix.smem* was removed as done later
in viafb_setup_fixinfo.

This patch highlights that the only usage of the ioremapped video memory
in the driver is for hardware cursor handling.  Even if it has to hold the
used virtual screen mapped for old-fashioned read/write calls (vs. 
mmap'ed) a lot virtual memory could be saved by only ioremapping on
demand.
